The tests on a four-ball friction machine have proved that introduction of 0.5–1.5 wt % ethanolamines makes possible to enhance 1.2–1.4 times the wear resistance in the calcium composite plastic lubricating materials incorporating a dispersion medium in the form of intermediate oil-refining products not subjected to a special refinement. In particular, these can be the vacuum oil distillates, in which all other properties remain invariable. As opposed to traditional high-purity industrial oils, this phenomenon occurs in the vacuum oil distillates because they contain small amounts of naphthenic acids that form ethanolamine soaps during interaction with ethanolamines. These soaps generate the formation of friction-induced boundary layers that show strong screening properties, which promote a lower wear of the contacting surfaces. © 2015, Allerton Press, Inc.
